What sslcertificates.io can do
Generic SMTP is the baseline transactional mailer. Test connection authenticates, sends a probe, and records provider responses without logging the password. Capabilities: send, test, health. Authentication uses smtp.
Required permissions
SMTP credentials stored encrypted. STARTTLS or implicit TLS.
Setup
Open Dashboard → Integrations → Generic SMTP. Enter the credentials described on this page. Values are encrypted at rest and never shown again. Run Test connection. Discovery runs only after authentication succeeds. Select a discovered resource. Do not paste opaque IDs unless the provider cannot enumerate them. Perform the certificate or notification action, then confirm the external system matches. Disconnect removes stored credentials and owned test resources created by sslcertificates.io.
Known limitations
Open relays are rejected. Test sends a message to the organization's billing or admin email.
